As a duke I am yet to recieve a message like that on Beluaterra.
As for removing lords, it would sometimes be handy, but I am not requesting it nor hoping that it becomes part of the game.
I had had a discussion with another duke who viewed regions in a duchy to be similar to estates in a region. It was suggested that being able to kick a lord was a feature that was in the works. "if they can be appointed they should be able to be removed" was the statement.
